IMPROVEMENT IN'GRAIN-BVINDERS.

Specification forming part of Letters Patent No. 118,786, dated J une 13,1876 application filed March 23, L876.

To all whom it may concern:

Be it known that I, SYLvANUs D. LOOKE, of Hoosick Falls, in the county of Rensselaer and State of New York, have invented a new and useful Improvement in Back and Pinion,

That others may fully understand my improvement, I will particularly describe it, having reference to the accompanying drawings, wherein- Figure 1 is a transverse section of my bindin g-machine and the adjacent parts of my harvester, showing the operative mechanism of my device in position. Fig. 2 is a perspective of the rack and pinion in position. Fig. 3 is a front elevation of the upper end of the pinion-shaft, showing the manner of its support upon the binder-post. Fig. 4 is a plan of the upper bearing of the pinion-shaft with the stop-plate and lever-crank.

F G' is the main frame of the'harvester. E

' is a shafttaking motion from the main wheeland communicating the same, through the wheel q and shaft on and wheel b, to the shaft B, which propels the bindingand compressing arms. A is the main post of the binder, which supports'the bearings for the shaft B. It is firmly bolted to the base-plank O. D is the cradle or receptacle of the binder, into which the grain is deliveredby the endless carrier or elevator. His a bar of the elevatorframe, to which rails h are attached for the support and guidance ofthe upper end of the binder'frame. The lower part of the binderframe travels upon rails g, which are angled or L-shaped in cross-section, and fit feet or brackets e, which are correspondingly notched, so that, when once in position, the said feet may freely slide lengthwise upon said rails,

but cannot become detached therefrom, ex-

cept by sliding ad the ends thereof, which it may, as shown, Fig.2.

- The fbregoin g is descriptive of the structure which I have at present-adopted, and which is shown in the accompanying drawings; but-I do not design to be limited to the application of my device to the details of structure shown, as the same may be varied indefinitely without in any way affecting the operation of myimprovement.

At the rear end of the binding-machine I 10 Fig.2. It may, however,beseparated,formed,

and attached in any suitable manner.

It is manifest that the revolution of the shaft Ijwill cause the foot 0 and the binding-machine to move forward or backward, according to the direction of said revolution, and said revolution is produced, at the will of the attendant, by means of cranlclever M, attached to;

the upper end of the shaft I, and convenient- 1y within reach of the drivers hand while upon his seat. The lever M is pivoted to the shaft I, and upon its lower side there is a small stud, m, which engageswith one of a series of notches, a, in the flattened disk-like top of the bracket J, through the center of which the'shaft I passes. The engagement of said stud and notch serves as a lock to hold and retain the binder in any desired position, because said lock prevents the turning of the shaft I, and the engagement of the rack and pinion prevents any forward or backward movement without'a revolutionof said shaft.

When the binder is to be moved itis merely necessary for the driver to raise the outer end of the lever M, and rotate it and the shaft I until the desired adjustmentis obtained. The

I weights of the lever M will cause it to look as soon as released from the hand. I

Having described my improvement, what I claim as new 1s- 1 I 1.: lheyfrotaryshaft, L heping thereonj an operating lever and; a. pinion, lnonntfedflipon and removable with an automatic adjustable binding-machine, oombined with a stntiopai y rack upon the harvester-frame,- With which said pinion is in mesh, for the purpose set forth. i p 1 2. The shaft I onthe bindingfframe, having the pinion K at its lower end. to engage with raekL, and weighted leVer'M, proi ided'with a stud, m, at its upper end, and the locking plate provided with notches, as set forth,

3. The'foot e, having the LshzipeGnotChtO shaft I. p i

, t, The rail g, havingmi L-shaped flange,as

and for the purpose set forth, and the rack L, all cost in one piece, in connection with the pinion K and shitft L te-adjust the binding-y machine, as set forth.
